Here's my recommendation: don't stay so Lomg at either place. Got to thuatmos and moored. You'll be bored at tahaa and the food is terrible there. i spent 6 days in tahaa and it was three days many. If you stay for six days, work on your tennis, download several New Yorker issues on your iPad and save a tv series to binge watch.
split it up more. Seriously. If you use my ta who posts here and he said only two islands I'll slap him myself. Go to thuatmos for something a little more.
Pasinius will back me up on this.
